CHARLES BARNES, OF CINCINNATI, OHIO.

Letters Patent No. 76,584, dated April 14, 1868,

IMPROVEMENT 1N Visas.

TO WHOM IT MAY CONCERN:

'Be it known that I, CHARLES BARNES, ot' Cincinnati, Hamilton eounty,and State of Ohio, vhave invented a certain newAa-nd useful Viso; and do herebypdeclare the following to be a full; clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

This invention relates to a construction of bench-vise, which, in its most com pleteform, is adapted tol hold a great variety of' objects in any desired position, and comprises a pair otjaivs adjustable toward and from one anothbr in a horizontal plane, andalso capable ot angular er rotary adjustment about a vertical as Well as around a horizontal axis. I

Figure 1 is a perspective View of a' bench-vise embodying my invention.

Figure 2 is an axial section of tlie same in the linea: x. u

Figure Sis an axial section in the line y y.

Figure 4 is a side elevation thereof.

A represents a portion of a bench, having a rounded edge, a,'.to permit ot' any desired horizontal vibration of the vvise, and being traversed vertically by the shank B, secured by nut b, of a cylindrical yoke, C, which is parted, c, on vone side, and provided with' ears, D'D, traversed by a screw-bolt, E, whose screw-threaded portion is-tapped into the lower ear, D,'.so'as to enable the lips ot' the parting to be closed toward each other, and to thus firmly gripe the tubular stem F of the rear cheek. G.

Fitted snugly within the cylindrical interior ot` the stem F is the stem H of the front cheek I, which stem is likewise tubular, to receive the main screw J' and spiral spring K. The stem H is slotted, 7i, to permit the traverseiof a nut, L, which is attached to and projects within the stein F, and into which the main screw, J, is tapped; The slot 7L and nut L eo-act to hold the jarfs'in accurate opposition, and likewise admit of their approach and separation.

M M are the customaryjaws, and, from these, the cheeks are prolonged beyond the stems, and are armed with V-forined or angular jaws N N for griping pipes and other round objects. v

It will be sc'en that the tivo cheeks of this vise are susceptible of being vibrated bodily through about ninety degrees, or more,vin a horizontal plane about the shank B, and are susceptible of complete vertical rotation about the shank F. j

This arrangement enables the resting of one end ofa pipe, of any length, in any convenientposition upon the ground, while the other end is irmly'and conveniently held inthevise, audit also enables the work to he pre sented in various convenient positions without being removed it'rom the vise, and the nut and screws E and enable the checks to be securely held to any position of adjustment whatsoever.

The spiral spring Ii serves to hold the cheeks to any position of separation permitted by the main screw.

I do not propose to restrict the invention to the precise form here shown, the same being susceptible-of various modifications; t`or example, thestem F and yoke E may be spherical, instead'of cylindrical, at their place oi' contact, the yoke being parted on both sides, and secured by two bolts.

I claim herein as new, and of my invcntion- I 1. A bench-vise, adjustable around tiro centres, at right angles to each other, substantially as set forth.

2. The arrangement of cheeks G and I, with tubular stems F and H, capable of being slid one within the other, and secured within the divided yoke C, vibrating about a vertical stem, B, in combination with the nut b and screws E and J for regulating and fixing the adjustments.

In testimony of which invention, I hereunto sct my hand.
